STOP-COCK Box FOR WATER AND GAS PIPES.

i SPECIFICATION vforming part of Letters Patent No. 326,674, dated september z2, 1885.

` i Appiiauon filed April 17, 1884. (No model.)

Be it known that we, LoUIs P. BEICHERT and ANDREW FULLER, both of the city of Buffalo, in the county of Erie and State of New York,have invented new and useful Improvements in Stop-Cock Boxes for WVater and Gas Pipes, of which the following is a specification.

This invention relates to an improvement in that class of telescopic tubular boxes or casings which are employed in connection with the street-cocks of gas or water pipes for the purpose of permitting ready access to the cocks whenever required.

The object of our invention is to provide a simple means for adjusting the length of the telescopic box or casing, to attach the cover to the box securely, and so as to be readily removable, and to construct the foot of the box in such manner as to exclude the earth from the interior of the box as much as possible.

With these ends in view our invention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figures l and 2 represent vertical sectional elevations of our improved box at right angles to each other. Figs. 3 and 4 are horizontal sections in lines x and y y, Fig. l, respectively. Fig. 5 is a perspective view of the cover. Fig. 6 is a perspective view of the washers.

Like letters of reference refer to like parts in the several figures.

A represents the upper or outer tubular part of the box,and B the inner or lower part thereof,tted loosely within the part A, so that the latter can be freely raised and lowered in adjusting the length of the box.

a is a vertical recess or groove formed in the outer part, A, on its inner side, and b represents two vertical rows or series of horizontal stops or ribs formed in the recess a, on opposite sides thereof, leaving between them a clear space, c. The ribs of one series are arranged opposite the spaces between the ribs in the other series, as clearly shown in Fig. 2.

d represents a stud or projection formed on the upper end of the lower part, B, and made of such size that it will freely pass through the clear space o between the two rows of ribs b, and so that it will enter the space between two ribs of the same row. Upon turning the upper part, A, so that the stud coincides with the space c between the ribs b,t-he upper part, A, can be raised or lowered on the lower part, B,to adjust the height of the box. When the parts have been adjusted, they are locked in the desired position by turning the part A so that the stud cl enters between two of the ribs b.

Instead of two rows of ribs .11, a single row may be employed; but by arranging the ribs b in two rows, so as to break joints,aiiner adjustment is rendered possible. The outer side or back of the groove ais closed, thereby affordin g a firm bearing against the surrounding earth, and preventing the latter from working between the ribs b and clogging or obstruct-4 ing the same.

E represents the cover resting upon the upper end of the upper tube,A,and provided with a marginal fiange, e, which overlaps the tube A.

F is a hollow ear or projection extending laterally from the upper end of the tube A, and

fis a depressed ear or tongue formed on the cover E, and projecting into the extension F when the cover is applied to the tube A.

G is a turn-button arranged on the bottom of the hollow extension F, and secured to the lower end of a bolt, g, which turns in openings in the top and bottom plates of the extension F. The boltg is provided above the top plate of the extension F with a head, h, to which a wrench can be applied for turning the button G. This head is preferably made five-sided to render it diiiicult for unauthorized persons to turn the button and remove the cover. Upon turning the button G,so that it engages under the tongue f,the cover is snugly locked in place. By giving the button a quarter-turn the tongue is released, when the cover can be removed.

H represents the iiaring base or foot formed on the lower end of the lower pipe, B, and provided with notches h, through which the servicepipe passes.

I represents sliding bottom plates moving in horizontal ways or grooves i, formed along the lower edges of the foot I, and adapted to be closed under the service-pipe after the foot of the stop-cock box has been placed over the pipe.

The plates I form a closed bottom under- IOO neath the pipe, and prevent the soil from workingkup intothe boxand obstructing the stopcoc J represents washers applied to the outer side of the foot H around the service-pipe to close the notches h of the foot. These washers are each composed of two parts, provided on their contiguous sides with semicircular notches j ,which entirely inclose the pipe. @The depression, a, closed on the outer side of the tube, and having onv its inner side ribs b,adapt ed to interlock with the stud d, and aclear space, c, forthe passage of said stud,substantiallyfassetorth.

2. The combination,with the inner tube, B, having` a stud or projection, d, of the outer tube, A, having on its inner side a vertical groove or depression, a, provided with two rows of ribs, b, arranged -to break joint,land an intermediate clear space, c, substantially as set forth.

3; In astop-cock bo'x,the combination,with the upper tube,A,provided with ahollow ear, F,closed at the top and` open at its innerside, of a turn-button, G, pivoted in said ear, and a cover, E, provided with a tongue, f, adapted to be locked by the turn-button against the top of the hollow ear,substantially as set-forth.
